The Solution for Comfortable Living with Ranch Sliders

Many Kiwi homes still rely on single-glazed ranch sliders, which can be a major source of heat loss and noise. While these large sliding doors are ideal for indoor-outdoor living, they often let in cold drafts and unwanted sound.

Retrofitting your existing doors with double glazing for ranch sliders can make your home significantly warmer, quieter, and more energy-efficient – while also lowering power bills.

Magnetite offers tailored retrofit double glazing for ranch sliders, using proven systems to improve comfort and performance. We assess your current doors, custom design a solution, and install it with care – all without replacing your existing frames or doors

With over 25 years of experience, Magnetite serves homes across New Zealand through a reliable network of licensed estimators, fabricators, and installers, primarily in the North Island.
